Don't worry, I did a bit of mapping too.
Actually the site I was picking up the LTE from was the site at 71/36 (it actually sits on South B & K Rd). I will have all the screenshots up in a few minutes
I drive by that tower all the time on my way to work, It's not but a couple of miles from where I live. I will try to stop by later and see if I can pick up any LTE on it.
As far as 800 in Centerburg, I can confirm this. I drive route 3 from Sunbury to Mt Vernon for work and I pick up 800. The LTE does not make it to route 3 though, mapped it all the way to work on Thursday and only got 3G.
I'm hoping i may have some good news from Sunbury soon, normally I have amazing coverage in my apartment (5 bars at all times) but for the last couple of days i have been kicking in and out of roaming, here's hoping.
I seem to be as lost as everyone else right now on all of the issues this weekend, but I usually have 5 bars at my apartment in Sunbury and all I can pick up right now is a roaming signal. I'm not getting my hopes up because I assume they probably wouldn't be working that far north yet but who knows....maybe.
